New Zealand research peptide supplier report, September 2026

Key findings

1. 01

   65 stores sell to buyers in New Zealand. 3 are based in New Zealand and 62 ship in from abroad: 1 from Denmark, 32 from the UK, 1 from Lithuania, 8 from the US and 20 that do not say where they are based.

2. 02

   78% of stores selling to New Zealand say their products are third-party tested; none of those claims has been checked yet. 51 of the 65 stores selling to New Zealand (78%) say on their own website that their products are third-party tested, and 48 link a page of certificates of analysis. PepFinder has not yet reviewed a certificate from any store serving New Zealand, and one store serving New Zealand has passed a PepFinder staff check. These are the stores' statements, not results we have confirmed; stores may hold certificates we have not seen.

3. 03

   Most listings sold to New Zealand are priced in other currencies. These stores list 2,849 products, but only 80 are priced in NZD; the other 2,769 are in other currencies and are left out, never converted. Of the 80 NZD listings, 47 (59%) state a price, form and quantity we can compare.

4. 04

   Too few prices in NZD to compare yet. No peptide has at least 5 validated NZD listings from 3 stores, the minimum we publish a price figure from. The report will add price distributions once stores serving New Zealand list enough prices in NZD.

Which prices can be compared

Every listing priced in NZD by a store serving New Zealand, by what we could read from it. Only the first row enters any price figure. 2,769 more listings from these stores are priced in other currencies and are not included.

Of the 47 compared prices, 47 are single vials and 0 are packs of several vials. The price figures below use single vials only, so a bulk price is never set against one vial.

How the figures are built

Stores serving the region

Published, active suppliers based in the market or stating they ship to it.

Based in the region

The supplier's recorded country is in the market.

Third-party testing

What the supplier's own website states. 'stated' is a claim, not a verified result; 'notFound' means we read the site and found no such statement; 'notAssessed' means not yet read.

Certificates page

The supplier's site links a page of certificates of analysis. Not a check of any certificate.

Certificates reviewed

Suppliers with at least one certificate PepFinder holds and has reviewed.

PepFinder check

Suppliers with a PepFinder staff verification check passed and not expired.

Compared price

Listed price in the market currency whose form, total mass and currency we could read with confidence, not held for review and not an outlier. Only VALID prices enter the distributions.

Single vial

One vial of powder of one peptide. Packs of several vials, pens, capsules, sprays, kits and blends are excluded from the distributions.

Minimum sample

A peptide is reported once it has at least 5 listings from 3 suppliers.

One business, several sites

A business trading through several confirmed storefronts is counted once per identical listing.

Prices are listed prices as each store's site showed them when last checked, without shipping or tax. Nothing here describes what the products do or how they are used; they are sold for laboratory research. How we collect and validate prices · Legal status in New Zealand.
